It’ s a beautiful treasure chest with the radio inside that switch on when you open the cover.

This set has the standard broadcast band only and works with direct amplification coupled cascade stage circuits.

The little brass button that you see on the control panel is used to remove the sound without switching off the radio.

Pulling up this button you cut off the signal from the low frequency unit, all the tubes remains lighted up and the radio is in stand-by condition.

To reactivate the volume you have just to push the button and the sound back immediately.

 

In this radio were originally used the famous Eveready Raytheon tubes:

ER551 - ER551 - ER224 - ER247 - ER280.
